In just over a month we will make some changes to our privacy policies and Google Terms of Service. This stuff matters, so we wanted to explain what’s changing, why and what these changes mean for users.

First, our privacy policies. Despite trimming our policies in 2010, we still have more than 70 (yes, you read right … 70) privacy documents covering all of our different products. This approach is somewhat complicated. It’s also at odds with our efforts to integrate our different products more closely so that we can create a beautifully simple, intuitive user experience across Google.

So we’re rolling out a new main privacy policy that covers the majority of our products and explains what information we collect, and how we use it, in a much more readable way. While we’ve had to keep a handful of separate privacy notices for legal and other reasons, we’re consolidating more than 60 into our main Privacy Policy.

Regulators globally have been calling for shorter, simpler privacy policies—and having one policy covering many different products is now fairly standard across the web.

These changes will take effect on March 1, and we’re starting to notify users today, including via email and a notice on our homepage.

What does this mean in practice? The main change is for users with Google Accounts. Our new Privacy Policy makes clear that, if you’re signed in, we may combine information you've provided from one service with information from other services. In short, we’ll treat you as a single user across all our products, which will mean a simpler, more intuitive Google experience.

Our recently launched personal search feature is a good example of the cool things Google can do when we combine information across products. Our search box now gives you great answers not just from the web, but your personal stuff too. So if I search for restaurants in Munich, I might see Google+ posts or photos that people have shared with me, or that are in my albums. Today we can also do things like make it easy for you to read a memo from Google Docs right in your Gmail, or add someone from your Gmail contacts to a meeting in Google Calendar.

But there’s so much more that Google can do to help you by sharing more of your information with … well, you. We can make search better—figuring out what you really mean when you type in Apple, Jaguar or Pink. We can provide more relevant ads too. For example, it’s January, but maybe you’re not a gym person, so fitness ads aren’t that useful to you. We can provide reminders that you’re going to be late for a meeting based on your location, your calendar and an understanding of what the traffic is like that day. Or ensure that our spelling suggestions, even for your friends’ names, are accurate because you’ve typed them before. People still have to do way too much heavy lifting, and we want to do a better job of helping them out.

Second, the Google Terms of Service—terms you agree to when you use our products. As with our privacy policies, we’ve rewritten them so they’re easier to read. We’ve also cut down the total number, so many of our products are now covered by our new main Google Terms of Service. Visit the Google Terms of Service page to find the revised terms.

Finally, what we’re not changing. We remain committed to data liberation, so if you want to take your information elsewhere you can. We don’t sell your personal information, nor do we share it externally without your permission except in very limited circumstances like a valid court order. We try hard to be transparent about the information we collect, and to give you meaningful choices about how it is used—for example our Ads Preferences Manager enables you to edit the interest categories we advertise against or turn off certain Google ads altogether. And we continue to design privacy controls, like Google+’s circles, into our products from the ground up.

We believe this new, simpler policy will make it easier for people to understand our privacy practices as well as enable Google to improve the services we offer. Whether you’re a new Google user or an old hand, please do take the time to read our new privacy policy and terms, learn more about the changes we’re making and understand the controls we offer.
